In an interchangeable assembly,a shaft of 20+0.015-0.05

In an interchangeable assembly,a shaft of 20^+0.015^-0.05 mm diameter and a hole of ^+0.025^-0.010 mm diameter form a mating pair. In the worst assembly conditions, clearance between them will be

In worst assembly condition, clearance will maximum
Clearance (max) = Max hole dia – Minimum shaft diameter
= 20.025 – 19.995 = 0.030 = 30 microns
